When I go out to my car, (parked in the gargage) in the morning and open the back doors to put my kids in the interior lights only stay on for a few seconds and then go out. Does anyone know how to change this? It's annoying trying to buckle them in with no lights. Btw, I asked my service adivsor and he told me it's in the menu settings. Absolutely no help.

Thanks for the help.

 

It was possible in W203 to adjust the timer from instrument cluster.
Maybe in engineering menu you can alter the lighting timer for W204.
